IMPROVEMENT IN VALVE-COCKS. v

The Schedule referred to in these Letters Patent and making part of the same I, J .inns WILSON, assignorto WILLIAM SlMoN,

Sylvania, have invented an Improved Valve-(lock, of which the following is a specification.

Nature and Object the I uren tion.

My invention consists of a faucet or stop-cock, in which a valve is hinged to the interior of the casing, and controlled by a screw spindle, substantially ill the lnalmer described hereafter; also ill so constructing, arranging, and adapting the parts to each other, that while a most elicient means 'of operating the valve is pensed with.

My invention further consists of improvements described hereafter in packing the faucet or stop-cock.

Description of the Acconlpany-ing Drawings. Figure l is a vertical section of a i'aucet, showing luy improvements, and the valve depressed;

Figure 2, the same, showing the valve elevated; Figure 3, a sectional plan on the lille 1-2, fig. 0'; and 4 Figure 4, a detached view of the valve'and its ad- Gcneral Description.'

As regards external shape and interior arran gement, the body of the faucet is similar to those in colnlnoll use, as it consists of the valvechamberA, and curved branch, B, the interior of whicll. is separated from the interior of the inlet branch B 'by a'p'artition, a, which has the usual opening b, and which forms the seat for the valve G.

'.lothe top of the casing A is adapted a screw cover, E, a packing-ring, d, wit-hin which bears on the upper edge ofthe casing, and also on a metal disk, F, litted in a recess forlned within the said casing.

From the under side of the disk F, and forming part of the saure, projects all arm, f, which so fits in a ver-- tical groove in the inside of the casing, as to prevent the disk fl'om being turned therein.

This Varm ftcrnxinates at its lower end in a pocket which forms the bearingfor the T-shaped head of the projection h4 on the valve G, so that the latter-is hullg looselyto, butconiined to its place witllin the casing by the said pocket. Y

H is the valve-sl'lilldle passing through thecover E, and through the disk F, which acts as tbe stationary nut for the screwed portion in. ofthe valvefspindle.v

Below the screw, the spindle is reduced in diameter, so that a recess, x, may be there formed, and the spin-- dle terminates below this recess in a rounded end, i, which bcarsupon the valve under the circumstances described hereafter'.

Two fingers, a n., project from the top of the valve,

and the bent ends 11p of these lingers project illto the recess of the spindle, as sllowll in iig. 4, so that on unscrewing' the spindle, the valve will be raised, as shown in lig. 2. On screwing down the spindle, however, its lower end will bear ou the top ofthe valve, and depress the latter to its scat, as shown ill fig. 1.

It` sllould be understood that the valve is very loosely connected to the armf, and also to the spindle, sothat it may have sulicient freedom to heal' truly with its fa-ee ou the seat a.

Above the disk F is an annular projection, g, which enters the cover, and to this projection isiitted alnetal ring, s, which, healing against a suitable packing, 11, lod lfedin the inside ofthe cover will irevent all leakage between the lattel and the spindle.

x of the spindle, before the introduction of the valvespindle and disk into the easing, and after such introduction the valve is as elfcctually alld permanently hinged to the casing and connected to the spindle as y if lllol'e costly appliances had been used.

' under the control ofthe spindle, may be applied to stopeocks generally. v v

Claims.

1. A faucet or cock in which the valve is hingedat one edge within the casing, substantially as described, and is connected toa rotating spindle so as to heraised and depressed by the latter as speciiicd.

2. The combination with the casing, of adetachahlc disk, F, and a valve,-G, bling to a projection' oli the disk, substantially as specified.

-3. Tile combination of the disk F, casing to which the disk is fitted, cover E and packing as set forth.

4. rIhe rings interposed between the projection g and packing 19, as described.

5. The valve G, hung at one side within theeasing, having bent lingers 'a n, and operatingin eoll'lbilu-ltion with the recessed screw spindle as specified.

In testimony whereof, I have signed my llallle to this specitcation in the presence ot two subscribing witnesses.
